The hypotenuse of a right triangle is 6 inches longer than the shortest side and 3 inches longer than the remaining side. Find the dimensions of the triangle\r
\n" ); document.write( "\n" ); document.write( "----------------------------------------------------------------------------------\r
\n" ); document.write( "\n" ); document.write( "Let S be the short side of the triangle.
\n" ); document.write( "Then S+6 is the hypotenuse.
\n" ); document.write( "And, the remaining side is S+3 because it's 3 inches shorter than the hypotenuse.\r
\n" ); document.write( "\n" ); document.write( "So, using the Pythagorean Theorem: \"S%5E2%2B%28S%2B3%29%5E2+=+%28S%2B6%29%5E2\".
\n" ); document.write( "Square everything and we get \"S%5E2+%2B+S%5E2%2B6S%2B9+=+S%5E2%2B12S%2B36\"
\n" ); document.write( "or \"2S%5E2%2B6S%2B9+=+S%5E2%2B12S%2B36\".
\n" ); document.write( "Subtract \"S%5E2\" from both sides: \"S%5E2%2B6S%2B9+=+12S%2B36\".
\n" ); document.write( "Subtract 12S from both sides: \"S%5E2-6S%2B9+=+36\".
\n" ); document.write( "Subtract 36 from both sides: \"S%5E2-6S-27+=+0\".
\n" ); document.write( "This factors into \"%28S-9%29%28S%2B3%29+=+0+\".
\n" ); document.write( "So, \"S=9\" or \"S=-3\". But, S can't be negative, so \"S=9\".\r
\n" ); document.write( "\n" ); document.write( "Verify that \"S=9\" is correct.
\n" ); document.write( "\"S%5E2%2B%28S%2B3%29%5E2+=+9%5E2+%2B+12%5E12+=+81+%2B+144+=+225\" which is indeed \"15%5E2\".
\n" ); document.write( "
\n" );
